SPECIFICATION forming part of Letters Patent No. 363,004, dated May 17,1887.

Application filed January 13, 1887. Serial No. 211,928. (Model.) l

.To @ZZ whom, it may concern:

Be itknown that I, LO Urs SOHUTTE, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certainImprovements in Steam -Injectors, of which the following is aspecification.

This invention relates to that class of jet apparatus which comprise asthe leading elements an aetuatingnozzle,a combining-tube in which theactuating-Huid and the :fluid to be moved are brought in contact, and adischargetube expanding in the direction ofthe delivery.

The objects of my present invention are, rst, to provide the instrumentwith such inlet and outlet passages and means for attaching pipesthereto in a variety of positions and directions that the attachment ofthe instrument is greatly facilitated, the use of eXtra elbows avoided,and space eeonomized; second, to provide improved facilities for theready adjustment of the instrument to the performance of the particularduties required, and to admit of these adjustments being effected byunskilled labor withoutthe possibility of placing the parts in aninoperative position.

In the accompanyingdrawing the figure represents a longitudinal centralsection through a steam-injector having my improvements incorporatedtherein.

Referring to the drawing, A represents the body of the instrument,B thenozzle for the actuating-Huid, C the combining tube or nozzle, and D thedischarge-tube. Vith the exception of the peculiarities hereinafterdcscribed, the parts are of ordinary construction and arrangement, thenozzle B being arranged to deliver the actuating-fluid centrally intoand through the mixing-tube C, which in turn delivers through the tube Din the direction indicated by the arrow.

In order to adapt the instrument for the couvenient application of thedischarge-pipe in different positions, as may be required underdifferent circumstances, I provide the body A at one end with the twodelivery-openings, E and E', having their axes at right angles to eachother, the first passin'g through the side of the body and the secondpassing through its end directly opposite the discharge-tube D. The twoopenings are made of equal diameter and threaded alike, in order thatone or the other may be closed at will by means of a plug, G, providedfor the purpose. rlhe dischargepipe may be screwed into either 011e ofthe openings, as circumstances may demand, and the other opening closedby the pino".

In order to permit the application of the steam-supply pipe in differentpositions, I pro` vide at the receiving end of the apparatus twointernally-threaded openings, H and H, one in the end and the other inthe side. These openings are of equal diameter and threaded alike, sothat the steam-supply pipe may be inserted in the one or the other, asoccasion requires. A plug, I, is provided for the purpose of closing oneor the other of these openings, as required.

By providing the instrument with the two openings for the receiving-pipeand the two openings for the discharge-pipe, and with the plugs adaptedfor transposition, as described, I adapt the same for ready attachmentin a11,or nearly all, positions which will be encountered, at the sametime avoiding the employment of the extra elbows and other connectionswhich are frequenti y demanded by the ordinary construction, and whichare for many reasons objectionable.

In order to permit the adjustment of the instrument for theperformaneeof its duties under different conditions, I provide a reversiblespindle, J, which may be threaded into the plug I, or into othersuitable support. This spindle has its two ends of different diameters,and isp rovided with aeentral collar and screwthreads c on both sides ofthe collar, so that it may be turned end for end at will, and screwedinto position with one or the other of its ends projecting into theactuating-nozzle B, as occasion may require. By the use of the largerend the steam-passage through the noz- Zie B is reduced. XVhen a largesupply of steam is demanded, the spindle maybe entirely removed.

It will be perceived that by means of theremovable and reversiblespindle three distinct adjustments may be given the instrument asregards the q nantityof the steam-supply. It

will also be observed that these adjustments may be effected byunskilled persons without ICO danger of rendering the instrumentinoperative.

Having thus described my iuvention,what I claim is- 1. In an injectorhaving a steam-nozzle, a mixing-tube, and adisehargetube, an externalbody inclosing and sustaining said parts, said body provided at itsdischarge end with duplicate threaded delivery-openings at right anglesto each other, and with a plug ehangeable from one to the other of saidopenings at w1 2. In aninjeetor containingasteamnozzle,a mixing-tube,and va discharge-tube, an internal body inelosing and sustaining saidparts, said body provided at itsend with duplicate openings at rightangles to each other, and with a Louis v soHU'r'rE.
